- `'Shaping machines have'been "so designed that the feed is adjustable :through hand-V graSp mounted coaxiallywitli'an oscillating member having afi box-like lfofri'nof aV moreor less rectangular .shape `bearing graduati'ofn'sv on its elongated front-face.

The aim of the present, invention is to carryforward .the advantageous character# istics of the aforesaid mechanismiby a neater structural karrangement i whereby the oscilla? j tory motion of vsaid Vmember `willbe less coni spicuous through a symmetrical form*v ofv a, substantially circular shape.` lIty isgalsofan object to effectian improve` ment in ,the means indicating'tlie extenty of feed by "arranging the graduationsfin the form of va dial; and -b`y soproportioniiig th e. parts-that a single revolutionv `ofV the hand#4 grasp will accomplishthe full extent of ad-A justment-thereby avoiding the necessity of turning the hand-grasp morethan. a frac- 'tional revolution forall degrees of adjust# Y inentwithin the fullextent of feed. Whilev bylocating the hand-grasp concenpart indicated in the following description 4G trically with the 'axisfof oscillation of the vmember on whichitis m0unt'ed,-it becomes much easier for the user :to inaketheadjust-v mentwhile the parts are inmotiom'it calls nevertheless Vfor some dexterity in inanipulation to set the adjustment preciselyto anyl selected graduation of? the scale and j anothery object of this invention is to increase the facility-with which that may be done by providing a detent so that the user `may by a sense of feeling set the hand-grasp quiclrly and precisely to anydesired graduation whiletlie parts are in motion.

Other objects andadvantages will be in and in part rendered apparent therefrom in connection with the annexed drawings To enable otliersskilled'in the artfso fully to apprehend the underlying featuresvhere-4 of that they may embody the same inl tlio various ways contemplated by this inven tion, drawings depicting a preferred typical construction have been annexed as a part of this disclosurefand, in such drawingsylilre characters ofreference denote corresponding parts throughout all the views, of which:

Referring tothe drawings, there is shown pivotally mounted on the side of'the'shaper a housing consisting of a round castingor shell 100 having laA circular cover y102, It

may be 'noted,iatthis pointfthatfthe shellv y 1003 has substantially all portions of vits pe riphery approximately at the `saine radial distance fromthe axis ofthe shell thereby giving this member a wheel-like form withf the advantagethat, whenit isirocked or oscillated aboutits aXis,zthe motionk is not conv spicuous and itsformation does not present any projections which, if :moved to and fro lin a circular path, would be likely to hit the userV of the machine. It may furthermore be noted that this formation `provides consid-` erable room forth'e vadmission cfa milling cutter duringtheprocess of manufacture iii which it is necessary to Acut the 'slideway 117. Also, by/reasonof the proportions given the shell 10.0,.it ismade possible to journal the adjustingscrew lldirectly inthe same; l

therebyH making` a more rigid .and `accurate carrierl ;illtliroughV a `suitable--mechanism A .which Lneednot be described inv orden to 'afford an understanding of'- this particular in-v vention.y l c i V n to the mechanism A `isvtransmitted through a link 42 in a manner described in my Patent :#1,267,158` issued May Y ally from a nut 115 which rides onfa screw` l" accomplish all "of the feeding rates.

It will beperceived'that, by .more orless.` rotatingv theliandgrasp 105 relative to the housing onl whichit is centrally journaled,

that the screw will be rotated through the gearing and the nut fed' radially an: appro pria'te distance from the center of oscillation; the nutfrbeing preferably interlitted with aV slideway 11'(4 `Lto maintain it in alignment.V

The cover 102 alsofprovid'es a vinarlzerior pointer`104 which indicatesthe extent to which the handgrasp 105 has been turned during the process beingall very conspicuously locatedV Cooperating with the visual graduations aforesaid' isa detent `arrangpment'for einA abling the user,through his sense of feeling, to turn the'handgrasp suiicientlyto bring any one of the divisions of the scale of gradd It will thus be perceived that this inven tion provides a Very simple structural organization which admits ofbeing readlly manuf factured and which when installed may be adjusted with great facilityduring the op-V erationijf the machine, andwhich will re mai'nin-its adjusted position, and which will be exceedingly neat and will not render conspicuous the .oscillatory movement duringthe running [of themachine; i. f Without further analysis, the foregoing will so ,fully reveal thefrist of this invention thiat'others can,1 by applying current knowledge, readily adapt itffor various utilizations by retaining one or more' of the features that, frlomthe standpoint of the prior art, fairly constitute essential characteristics of either thev generic or specific aspects of this invention,andjtherefore, such adaptations shouldbe, andare intended to be, comprehendedwithin the meaning and range ofequivalency of the following claim.

The lcover 102 provides a' hub "103 on the fend-face of which is a series of shallow holes 109 and a spring-pressed detent 108` is arranged, as shown by Fig. 3, in the hub of the (hand-grasp so that it may engageseleevtively any onerofthe aforesaid holes., The

end of the detent 108 is sufficiently rounded so that`,-while -i-t may easily be moved from one hole to another, it-Will serve to hold the handgrasp` 105 in;any position into which it hasy been adjusted andthereby prevent creeping orother displacement'of the hand-grasp relf attive to the hollow frame duringtheroperation of the machine..
